Investigations of B- and β-hematin
Journal of Inorganic Biochemistry, 1997The preparation from ferriprotoporphyrin IX (FP) in aqueous acid medium of the related pigments beta- and B-hematin [see G. Blauer and M. Akkawi, Biochem. Mol. Biol. Int. 35, 231 (1995)] is presented under different conditions. Both pigments are characterized by infrared spectra which differ in the range of 1600-1700 cm-1 in their strong bands with ...

Among the numerous throw-aways that the mailman delivers to my door are advertisements from pharmaceutical companies concerning drugs and related products. I recently received a set of complimentary starter prescriptions for a certain drug for the treatment of "iron deficiency anemia and megaloblastic anemia." The drug is composed of ferrous fumarate,

PEROXIDASE, HEMATIN, AND PEGYLATED-HEMATIN CATALYZED VINYL POLYMERIZATIONS IN WATER
Journal of Macromolecular Science, Part A, 2001Horseradish peroxidase-, hematin- and pegylated-hematin mediated polymerization of sodium styrene sulfonate and sodium acrylate in water is reported. Molecular weight and yields were influenced by the concentrations of hydrogen peroxide and initiator, 2,4-pentanedione.

Very rapid production in vitro of a particular type of hematin (B-hematin) with high yield at physiological pH and temperature is presently reported, using a simple chemical system including an organic acid in the absence of any enzyme. B-hematin is characterized by infrared spectra and solubility properties.

The toxicity of intravenously administered hematin (3.4 and 6 mg100 g) was investigated in rats, where an LD50 of 4.32 mg100 g was computed, with 95% confidence limits of 5.40 and 3.46 mg100 g. At toxic levels (4 mg100 g) the rats showed a drop of blood pressure, hemorrhages and renal failure, whereas lower doses were well tolerated.

Hematin: effects on hemostasis.
The Journal of laboratory and clinical medicine, 1990Extensive studies performed over the past 6 years have shown that a degradation product of hematin produces a unique coagulopathy, characterized by thrombocytopenia with platelet degranulation, alteration in the function of numerous clotting and fibrinolytic proteins, and reversible changes in endothelial cells. With the use of degraded hematin, it can
